Inner Tube Assembly
Inner Tube Assembly
Internal coating is applied to metal tubing to add lubricity, chemical isolation, or surface preparation to the tubing inside.
Samples available upon request.
The Inner tube is designed for internal coating applied to metal tubings like Torque coil, ACT ONE, or Wire coil for adding lubricity, chemical isolation, or surface preparation to the inside of the hollow cable. Ideal for applications requires lumen lubricity, sealing, or chemical resistance, for customers developing a delivery system.
Construction of Inner Tube
Specifications
Minimum wall thickness (including Fluoropolymer and PEBAX layer)
Coating material (Fluoropolymer layer)
- PTFE: greatest lubricity and chemical resistance
- PFA: similar in chemical resistance to PTFE, but less lubricity
- FEP: similar to PFA, slightly less susceptible to water absorption than others
- ETFE: greatest strength and abrasion resistance
Length: up to 1800mm (Trial : up to 3000mm)
End treatment of inner tube: manually cut using a utility knife
End treatment of outer cable: EDM cut, chamfering
